Incidence of overlap syndrome of functional dyspepsia and irritable bowel syndrome in Western UP

Abstract

Aim: To determine the incidence and risk factors for the clinical overlap between Functional Dyspepsia and Irritable Bowel syndrome defined by Rome IV criteria in Indian patients. Materials and methods: The present cross sectional study was carried out in ChattrapatiShivaji Subharti Hospital, Meerut in the Department of Medicine among consecutive patients with upper gastrointestinal symptoms who was referred for endoscopy. A structured questionnaire containing the FD and IBS modules of functional gastrointestinal disorders (FGIDs) and the putative risk factors for dyspepsia was administered to the participants. Results: Out of 500 subjects; FD, IBS and overlap was reported among 17.4%, 13.8% and 10.2% of the subjects respectively. Overall functional gastrointestinal disorders (FGID) were found in 207 (41.4%) subjects. Alcohol consumption was reported among 6.90%, 15.94% and 27.45% of the subjects having FD, IBS and overlap syndrome respectively. Hard or lumpy stools and defecation straining was reported more in subjects with overlap syndrome subjects followed by FD and IBS with statistically significant difference. Loose or watery stools was found least in FD subjects. A feeling of incomplete bowel movement was maximally revealed in overlap syndrome subjects. Conclusion: Patients having either FD or IBS overall have less severe symptoms and patients with overlap may represent the more severe symptoms as compared with FD or IBS.
